“Hey Fabio, thank you for welcoming me. The code below is the main app code that I’m trying to build. I have created the necessary EJS and JS files accordingly. Can you help me figure out how to check the database? I tried troubleshooting using Mongo Atlas documentation, but I’m unable to undo the action, as you can see in the screenshot below. The screenshot that is in the prior question shows the message ‘access control is not enabled for the database,’ and I think that’s the problem.
I’ve already started with MongoDB University courses.”
